Integrated Class-D Amplifier by ABLETEC, Norway: Achieves High-Quality Sound, High Output Power, and Low Power Consumption.
After month of technical research for an amp with high-quality sound and high output power to drive a full-scale speaker system with low power consumption, the ALC0180 Digital Power Amplifier module, manufactured by ABLETEC, Norway, was decided on to compliment the AI-501DA. Delivering a maximum of 90W + 90W of output power at a maximum 55W of power consumption, users are able to enjoy powerful sound without hesitation. Furthermore this next generation integrated amplifier consumes only 10W in idling mode, and 0.2W at power-saving standby mode.

Fully Digital Path via USB Cable allows 192kHz High-Res Audio Playback
Just connecting a USB cable between any Mac/Windows-PC and the AI-501DA, a variety of audio formats can be transferred in a fully digital manner. Once the driver software is installed, your playlist iTunes or Windows Media Player turn into part of your high-quality audio system. This allows 24bit/192kHz data transfer mode reduces jitter noise while the digital data travels along the USB cable.

BurrBrown PCM5102 D/A Converter for a Variety of Digital Sources
The AI-501DA employs the highly celebrated BurrBrown PCM5102, allowing 32bit processing across the USB audio input, Optical and Coaxial digital inputs. Parts were carefully selected for the analog circuits. The unit utilizes high-quality operational-amplifiers and electrolytic capacitors already proven on previous high-end models.

Large Capacity Toroidal-Core Power Transformer
An over-sized Toroidal-core power transformer helps deliver high-quality sound without sacrificing energy-efficiency and the unit’s compact dimensions. Conventional diodes produce rectification noise that negatively affects the sound of other units. To combat this, TEAC installed Schottky Barrier Diodes to supply a cleaner internal current and reduce rectification noise.

High-Quality Headphone Output Processed by an Exclusive Operational Amplifier on Each Channel
The AI-501DA is also designed for headphone listening, as well as speaker listening. An exclusive operational amplifier is employed on each channel. Conventional hi-fi systems only use a single operational amplifier for both channels.

No Cooling-Fan, for Quiet Operation
Effort to eliminate the signal to noise ratio and ensure high-quality audio playback mean nothing with a noisy cooling fan. To reach both goals to attain high performance and compact dimensions, TEAC carefully arranged the inner-workings to eliminate the need of a fan. There are two parameters that conflict with efficient heat dissipation, the circuit design and chassis design. After careful strategy, effective placement of potential heat-generating components allows this high-performance compact amplifier to operate without cooling fan.

A Full-Metal Construction and Small Footprint for Any Desktop Set-up
Not only the front panel, both side and top panels are made of aluminum panels and attached to a robust steel chassis. These heavy parts eliminate vibrations, and allow all internal circuits to always perform under stable conditions. An A4-size body allows users to place the unit small spaces. The AI-501DA defines a new standard that fits all modern interior with great space-saving design and a timeless presence.

Large Number Input/Output Allow Users to Integrate Full-Scale Hi-Fi System
The AI-501DA provides sufficient number of audio inputs allowing users to integrate full-scale hi-fi systems with both existing and future expansions. The device is equipped with two optical inputs and one coaxial input, along with two analog (two stereo) audio inputs. A set of large biding-post speaker terminals accommodates high-grade speaker cables up to AWG8 grade. A detachable AC cable with a 3-polar socket also allows user to upgrade to a high-grade AC cable.

Well designed User Interface
A firm-torqued volume with a machined aluminum knob, and toggle type main power switch give the user assured operation. The remote control gives the unit an elegant appearance and very precise volume control, paces of approximately 1.5dB. To help contribute to the musical atmosphere is the classiest characteristic of the AI-501DA, the dimmable backlight, and dual analog meters.
